Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will evaluate the intracellular pharmacokinetics and platelet effects of abacavir (ABC), lamivudine (3TC), tenofovir alafenamide (TAF), and emtricitabine (FTC) in persons living with HIV that are receiving these medications as part of standard HIV care. Participants remaining on ABC/3TC- or TAF/FTC-containing therapy will be on study for 4 weeks, and will have two visits: a screening visit and one short PK visit consisting of a single blood draw at week 4. Participants switching from their ABC/3TC-containing therapy will be on study for 3 weeks, and will have nine visits: a screening visit and 8 short PK visits consisting of a single blood draw at Day 0, 1, 3, 7, 10, 14, 18, and 21.
